Simple file verification. Simple file verification (SFV) is a file format for storing CRC32 checksums of files to verify the integrity of files. SFV is used to verify that a file has not been corrupted, but it does not otherwise verify the file's authenticity. The .sfv file extension is usually used for SFV files. [1]
File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum. This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files. A more popular approach is to generate a hash of the copied ...
List of file signatures. This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources. This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbers or Magic Bytes.
File integrity monitoring (FIM) is an internal control or process that performs the act of validating the integrity of operating system and application software files using a verification method between the current file state and a known, good baseline. This comparison method often involves calculating a known cryptographic checksum of the file ...

md5sum is a computer program that calculates and verifies 128-bit MD5 hashes, as described in RFC 1321. The MD5 hash functions as a compact digital fingerprint of a file. As with all such hashing algorithms, there is theoretically an unlimited number of files that will have any given MD5 hash. However, it is very unlikely that any two non ...
Message authentication code. In cryptography, a message authentication code (MAC), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity -checking a message. In other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed (its integrity).
Mandatory access control. In computer security, mandatory access control (MAC) refers to a type of access control by which a secured environment (e.g., an operating system or a database) constrains the ability of a subject or initiator to access or modify on an object or target. [1] In the case of operating systems, the subject is a process or ...
